     25     <!-- The repository contains a collection of downloadable items known as
     26          "packages". Each package has a type and various attributes and contains
     27          a list of file "archives" that can be downloaded for specific OSes.
     28 
     29          An Android SDK repository is a web site that contains a "repository.xml"
     30          file that conforms to this XML Schema.

     32          History:
     33          - v1 is used by the SDK Updater in Tools r3 and r4.
     34 
     35          - v2 is used by the SDK Updater in Tools r5:
     36             - It introduces a new <sample> repository type. Previously samples
     37               were included in the <platform> packages. Instead this package is used
     38               and and the samples are installed in $SDK/samples.
     39             - All repository types have a new <obsolete> node. It works as a marker
     40               to indicate the package is obsolete and should not be selected by default.
     41               The UI also hides these out by default.
     42 
     43          - v3 is used by the SDK Updater in Tools r8:
     44             - It introduces a new <platform-tool> repository type. Previously platform-specific
     45               tools were included in the <platform> packages. Instead this package is used
     46               and platform-specific tools are installed in $SDK/platform-tools
     47             - There's a new element <min-platform-tools-rev> in <tool>. The tool package now
     48               requires that at least some minimal version of <platform-tool> be installed.
     49             - It removes the <addon> repository type, which is now in its own XML Schema.
     50 
     51          - v4 is used by the SDK Updater in Tools r12:
     52             - <extra> element now has a <project-files> element that contains 1 or
     53               or more <path>, each indicating the relative path of a file that this package
     54               can contribute to installed projects.
     55             - <platform> element now has a mandatory <layoutlib> that indicates the API
     56               and revision of that layout library for this particular platform.
     57 
     58          - v5 is used by the SDK Manager in Tools r14:
     59             - <extra> now has an <old-paths> element, a ;-separated list of old paths that
     60               should be detected and migrated to the new <path> for that package.
     61             - <platform> has a new optional <abi-included> that describes the ABI of the
     62               system image included in the platform, if any.
     63             - New <system-image> package type, to store system images outside of <platform>s.
     64             - New <source> package type.
     65 
     66          - v6 is used by the SDK Manager in Tools r18:
     67             - <extra> packages are removed. They are served only by the addon XML.
     68             - <platform>, <system-image>, <source>, <tool>, <platform-tool>, <doc>
     69               and <sample> get a new optional field <beta-rc> which can be used to indicate
     70               the package is a Beta Release Candidate and not a final release.
     71 
     72          - v7 is used by the SDK Manager in Tools r20:
     73             - For <tool> and <platform-tool> packages, the <revision> element becomes a
     74               a "full revision" element with <major>, <minor>, <micro> and <preview> sub-elements.
     75             - The <beta-rc> element is no longer supported, it is replaced by
     76               <revision> -> <preview> and is only for <tool> and <platform-tool> packages.
     77             - <min-tools-rev> and <min-platform-tools-rev> also become a full revision element.
     78 
     79          - v8 is used by the SDK Manager in Tools r22.0:
     80             - It introduces the new <build-tool> repository type, which contains build-specific
     81               tools that were before placed in either <tool> or <platform-tool> (e.g. ant,
     82               aapt, aidl, etc.)
     83             - <tool> has a new "min-build-tool" attribute.
     84 
     85          - v9 is used by the SDK Manager in Tools r22.6:
     86             - It introduces a sub-tag for the <system-image> repository type.
